All aspects of convergence and picture settings are controlled as if you had the original remote. The keypad changes inputs so they're also included on the MX-800 just like the original remote. Also works with the Barco 1200 (at least).
Commands for this device are available as part of a system layout file.
This is the complete remote control, it's nothing fancy but gives you all you need to operate the projector remotely. I have confirmed that this file works with my 701s and it was confirmed by another user that it works with a BG1200 and also 800. I am pretty sure it will run any Barco CRT projector for that matter!
